KDE really slow on newly-built computer

Hi all. I'm new to Garuda Linux and loving it so far, but I'm having some issues with KDE being really unresponsive on my newly-built PC (Ryzen 5 5600X, Nvidia GeForce RTX 3060, 16 MB RAM). I would characterize myself as a Linux intermediate, maybe slightly more towards beginner, but I'm a complete noob in PC building. I'll try my best to summarize what I'm trying to fix below. Thanks in advance for any help.

After building my system, Garuda installed on it no problem. It picked up my Nvidia card, etc, without issues. However, I'm regularly experiencing significant slowdowns in KDE. Examples are:

  1. KRunner taking 10 seconds to load
  2. Tap meta, start typing, have to wait 5-10 seconds for text to appear
  3. Occasional application freezes. The mouse cursor is always available, but windows will freeze and become unresponsive for 5 seconds to ~1 minute.

I've also felt that I'm not getting quite the performance in games from my GPU that I would expect. I've seen occasional stuttering in Outer Wilds. Nothing crazy, but that combined with the stuttering in KDE--plus the fact that System Monitor never showed my CPU or RAM getting overloaded--led me down a path of troubleshooting my Nvidia driver. So here's what I've done:

  1. Installed the nvidia-fake-powerd package from the AUR, after finding this forum post. This didn't see any noticeable change.
  2. Installed the nvidia-all driver (not Vulkan, dkms), following instructions here. Again, no noticeable change.

I'm a bit out of ideas at this point and would love any recommendations. Thanks, all. Here's my inxi:

have you tried it with lts kernel


No, I'll give it a try. Thanks for the suggestion!

Is Baloo working in background?

Drives:    Local Storage: total: 1.86 TiB used: 846.59 GiB (44.4%)

Lot of data.

Check in terminal with top/htop.


I'd also check in the Garuda assistant if a btrfs balance is suggested. Although it's a new installation, with all this stuff maybe it is already needed.

I'm showing my age a bit, I think. I remember a time when RAM was measured in MB.

Yes, Baloo is working in the background. It's the top four processes in htop by MEM%, taking ~19%. It's top in CPU% as well, varying between 1% - ~25%. But my overall RAM and CPU usage seem fine:

I just switched over to the LTS kernel, and it doesn't seem to have improved things. Still seeing random slowdowns that don't make sense on this hardware. I'll try disabling Baloo and see if that fixes it.

Oh, re: LTS kernel, the way I switched over was to install linux-lts and linux-lts-headers. I have the dkms Nvidia driver. Then I switched to the LTS kernel on the grub screen and verified it's running LTS. Seems to all be working, but let me know if I did anything wrong, I guess.

Thanks, all.

Wait, many here started with KB :blush:
But I don't want to go oot..


I think you be fine if baloo is ready with indexing. I think zen is better for your hardware, but just test it :slight_smile:

Update: Looks like it was Baloo. I disabled it by unchecking "Enable File Search" in System Settings, rebooted, and everything is much snappier.

Next I'm going to try re-enabling it but unchecking "Also index file content". I'll be super bummed if that doesn't work, as I definitely want that type of functionality on my system.

Does anyone have any insight as to why htop / System Monitor weren't able to call this to my attention? I never saw RAM or CPU as a whole spike significantly when running Baloo. Watching the aggregate values for those definitely led me to look at the GPU, since they didn't seem to be having any issues.

and now we almost have Desktop CPUs with more Cache capacity than our HDDs did (already there for those who class Threadripper as Desktop, or those earlier than me an my 170MB HDD).

Where in System Settings, might I find "Enable File Search" ? I want to stop Baloo because it is running a lot.

balooctl disable (or just suspend)


Just load up system settings, then in the search bar on the top left, just type "search" and one of the options it will filter to on the left sidebar will be "File Search" - click on that, then disable. That is, if you want the GUI way of doing it.


Update update: I tested turning Baloo back on, and it was stuck at 97% index for a really long time. I ran balooctl purge and re-enabled Baloo (still without indexing file content, which I don't really need), and htop is looking good.

Thanks for the help, everyone! I really appreciate it! And loving this super snappy computer now. :grin:
